5SFP 630 Equivalent & Substitute Parts

Part Overview

The 5SFP 630 is a 630 mA, 250 V AC/DC fast-blow glass fuse cartridge in a 5mm x 20mm axial through-hole package, manufactured by Bel Fuse Inc. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and approval certifications to ensure direct interchangeability in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5SFP 630 are grouped into two categories based on electrical and mechanical compatibility:

Direct Equivalents (Identical Current Rating): Parts maintaining the 630 mA current rating, 250 V AC voltage rating, fast-blow response, and 5mm x 20mm package dimensions. These parts are fully interchangeable without circuit modification.

Similar Alternatives (Different Current Rating): Parts with different current ratings (6.3 A) that share the same voltage rating, response time, and package dimensions. These parts require circuit evaluation before substitution.

The following parameters determine substitution eligibility:

• Current Rating (Amps)
• Voltage Rating (AC)
• Response Time (Fast Blow)
• Package / Case (5mm x 20mm)
• Fuse Type (Cartridge, Glass)
• Mounting Type (Through Hole)

Parameter Comparison

Engineering Selection Recommendations

5SFP 630-R (Bel Fuse Inc.): This is the primary direct equivalent. It maintains identical electrical specifications (630 mA, 250 V, fast-blow, 35 A breaking capacity) and mechanical dimensions. The part is active in production with ROHS3 compliance and expanded approval certifications (CCC, CE, CSA, cULus, IMQ, SEMKO, VDE). DC cold resistance is 0.15 Ohms compared to 0.19 Ohms in the original part. This substitution requires no circuit modifications.

0217.630MXEP (Littelfuse Inc.): This part provides identical electrical ratings (630 mA, 250 V, fast-blow, 35 A breaking capacity) and is active in production with ROHS3 compliance. Approval certifications include CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. Physical dimensions are slightly larger (5.80mm diameter vs. 5.50mm, 22.50mm length vs. 21.00mm). DC cold resistance matches at 0.19 Ohms. Mechanical fit must be verified in the target application due to dimensional variance.

0034.1524.PT (SCHURTER Inc.): This part differs in current rating (6.3 A vs. 630 mA), representing a 10x increase. While it maintains the same voltage rating, response time, and package family, the higher current rating makes it unsuitable as a direct substitute. This part is listed as a similar alternative only and requires full circuit re-evaluation before use.

Frequently Asked Questions (FAQ)

Q: Can 5SFP 630-R be used as a direct replacement for 5SFP 630?

A: Yes. The 5SFP 630-R maintains identical electrical ratings (630 mA, 250 V AC/DC, fast-blow response), breaking capacity (35 A), and mechanical package (5mm x 20mm). The part is active in production with enhanced compliance certifications. No circuit modifications are required.

Q: What is the difference between 5SFP 630 and 0217.630MXEP?

A: Both parts share identical electrical specifications (630 mA, 250 V, fast-blow, 35 A breaking capacity). The primary difference is physical dimension: 0217.630MXEP has a slightly larger diameter (5.80mm vs. 5.50mm) and length (22.50mm vs. 21.00mm). Mechanical fit in the target application must be verified before substitution.

Q: Why is 0034.1524.PT listed as a similar alternative rather than a direct equivalent?

A: The 0034.1524.PT has a current rating of 6.3 A, which is 10 times higher than the 630 mA rating of the 5SFP 630. Although it shares the same voltage rating, response time, and package family, the different current rating makes it unsuitable for direct substitution. Circuit protection requirements must be re-evaluated if this part is considered.

Q: Are all substitute parts RoHS compliant?

A: The original 5SFP 630 is RoHS non-compliant. Both direct equivalents (5SFP 630-R and 0217.630MXEP) are ROHS3 compliant, as is the similar alternative 0034.1524.PT. RoHS compliance may be a requirement for new designs or regulated applications.

Q: What approval certifications should I verify for my application?

A: The 5SFP 630 carries CE, CSA, IMQ, SEMKO, UL, and VDE approvals. The 5SFP 630-R adds CCC and cULus certifications. The 0217.630MXEP includes CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. Verify that the selected substitute meets the specific approval requirements of your target application and regulatory jurisdiction.

Q: Can I use these parts interchangeably in existing designs?

A: The 5SFP 630-R and 0217.630MXEP are electrically interchangeable with the original 5SFP 630. However, the 0217.630MXEP has slightly larger physical dimensions, so mechanical fit in the PCB or fuse holder must be confirmed. The 0034.1524.PT is not interchangeable due to its different current rating.
